This where people get into trouble, we were always told and taught over the
shoulder and in the garbage can for both elements every 200 hours
on the meter.
The tattle tail indicators will lie to the user and become stuck not indication restrictions.
If a Duetz Fahr oil bath precleaner was used with a paper element filter the engines would not require
air filter changes for hundreds of hours of use.
Oil bath air cleaners are used on huge stationary diesel engines because they offer the least restriction and the highest filtration of combustion air and the same would be true with an oil bath precleaner with a turbine precleaner mounted on
the top of the oil bath air cleaner attached to the paper element air cleaner.
The manufacurers of paper elements do not even recommend doing washing or using air to clean them as paper used in the pleats becomes weaker over time and the more dirt they encounter the greater pressure gradient "suction" occurs in the outer elements paper.
I have seen inner and outer paper elements implode on diesel engines because they were not changed as often as they should be and when you see this occur on a $100,000.00+ Mercedes Benz V-12 water cooled, turbocharged and aftercooled diesel engine with a radiator that is the size of a pickup truck cooling two other Mercedes V 12 engines of the same type you know some poor maintenance man was overruled in changing the inner and outer filters by his cheapskate boss.
That is one of the major reasons they have trouble with locomotive engines because of the poor design of the intake combustion air fitration method where if they used oil bath precleaner's for the engines they would have near zero issues
and could operate smaller indirect fuel injection systems
The old saying is "you can pay me now or later" is still true.
So you are recommending using an oil bath pre-cleaner ahead of a dual element paper filter?? I concur. Except the cost will negate that quickly on a mowing tractor.
Your examples are spot on. For $100,000 engines.
Your examples are also spot on to support maintaining filters. Paper filters that implode are examples of very poor maintenance. If I were the mechanic that happened to I'd blame it on the white collar boss too. If they were cleaned, they would not implode. Even if improperly cleaned. They imploded because nothing was done and they plugged. The engine then had the air flow to suck the guts out of them.
